The field BPP (CTRL[3:1]) is: 0=1bpp, 1=2bpp, 2=4bpp, 3=8bpp, 4=16bpp, 5=24bpp, 6=16bpp, 7=12bpp. So you need to assign the value 5 (if you need 24bpp) to the BPP field of LCD_CONFIG_T struct. However this is not clear and it seems you can assign directly 24 to BPP. Maybe an enumeration is better in this case.
